I also am finding success with handbrake. MP4 file container, MPEG-4 video codec, AAC audio codec. I use a two-pass encode, target size of 400MB for a normal movie. Works flawlessly for me.

Some about tools (again), all free, windoze & kinda easy:
Handbrake, Avidemux (@Windows, I'm using GTK version) are imho some of the best solutions. Settings are... difficult & different for each program. New version of Handbrake won't work anymore at my XP, don''t know why. There are few more tools:
Format Factory is last I try. It is not kind of tool I like, but I have admit it is easy and did a good (and fast!) job, but I don't remember settings I put.
AllToAVI is proven to be ok, but I find it too much annoying for me.
Any Video Converter should be a good tool too (e.g. for subtitles):
I take my words back about eTeSoft converter. Found another program that is much better, less buggy and is free.

Any Video Converter (yes, that's how it's called). It supports many formats, can include subtitles on the video, allows to choose audio track and has many other options. It also has a very user-friendly interface. And more importantly - the free version doesn't lack any critical features that pro version has.

I highly recommend it. http://www.any-video-converter.com/products/for_video_free/
karma +1        works great with .mkv with subtitles

AVC works with subtitles, but bware of the format you choose. Sometimes, audio desyncs so you have to mess around until you find a format that fits well on the dingoo.

Thought i would add to this thread rather than make a new one....

I am new to Dingoo, and taking mine on Holiday (9 flight) so have on order some tfsd cards (inc mini adaptors).

I notice that although xvid play fine they do get a bit blocky at times, mainly dark scenes where there is no video date i.e black.

So i thought while the Dingoo does not play a 624X352 xvid as well as say a PS3 or DVD Player etc does,as far as quality. I may aswell compress video down to reduce file size to get more movies/tv on cards.

So my aim is to say reduce a 350MB 640 res Xvid to about half its filesize and res i.e 320x 175MB file.

I tried downloading Super Video but when installing it cant download files.

Handbrake downloaded fine, i have tested this would Super Video be better for the task?

Settings i have used in Handbrake are.

320x Video (aspect makes 320x172) MP4 Container, MPEG4 Video, default AAC audio 160 bitrate

Then i mess about with video settings such as filesize 175MB

Would you reconmend any better?

What advantage does 2 pass encoding make?

Should i try the constant quality setting instead or maybe set a bitrate if so which is best?

Thank You

I wouldn't recommend going much lower than 400MB. Quality is pretty questionable even at that rate. You'll have to experiment though, and see what you can live with. Also a 8gb microsd card can be had for a very reasonable price, and could hold more video time than battery time.

Thanks...

Yeah at the moment because the Dingoo uses internal memory thats nearly full with the preinstall stuff plus some games i installed, i only have a 512MB Mini Sd card.

I have loads of SD and Transflash/Micro but no adaptor :(

So i have ordered 2X4GB and 1X8GB Kingston kits that give you each a micro SD plus adaptors for mini and full sd.

How long does the battery last watching from full charge?

I have found maybe setting bitrate at 500 and res to 320 will do the job.

I have looked at a 175MB Video i convertered and the 350MB source on the Dingoo and when the dingoo is like in your lap or i.e 10-12" from eyes the quality is different but not massive compared to the filesize.

Now if the Dingoo played the main source Xvids as perfect as they would on say a PS3 (i.e less aftifacts) i would not bother converting, but as they dont play perfectly (have some mnior blockyness at times) then i may aswell downgrade them so i can get double.

For Cartoons it should be fine to reduce the video size to even less than half!

So a Movie could be compressed from 700MB to 350-400MB (half) where as a South Park/Family Guy/Simpsons could be downgraded more without much notice... so i should get cartoons that are 200MB down to 75-100 MB each and still look watchable.

I also think on some flights you can charge stuff so i may be able to keep console charged up.

You do not have to experiment anymore. The effect you're describing is 16 bit color (the Dingoo's screen/video chip is 16 bit color). True color is 24 bit or 32 bit. It will NOT (repeat: NOT) get any better than:
  • Re-encoding to AVI wrapping format, xvid/divx video (~ 800 kbps) with MP3 audio (128 kbps). OR:
  • Leaving your downloaded movies the way they were when you downloaded them! Expecially AVI's

Hi well i tried the original file on PC with 32bit and 16 bit and i never noticed much difference if any.

I understand the screen on Dingoo is only 16bit but i dont think the videos colour uses most of the 32 bit anyway.

What i still notice is that using a original file 350MB on PC then recoded to 175MB you can notice a difference in quality, on the Dingoo that difference in quality from 640X (1000BR) 350MB compared to 320X (400BR) 175MB file is not noticed as much, simply put it seems the loss of quality of the 640 on the 320 screen compared to 320 recode on 320 screen is not much at all.

Especially Cartoons, so what i am saying is for say Cartoons for the sakes of 1.5 min per file, i can reduce its 150-200MB size to even 1/3rd and on Dingoo you cant even tell.

you can with a none cartoon but as i said above not that much, so its worth the trade off.

End of the day i wont be playing these on large tv, as we can use a phone that has tv out and 720X480 Screen for that, or i may get a Sumvision Micro 2.

I am using Handbrake because Super Video wont download.

So movies are being recoded from Xvid to MPEG 4 with AAC Track, i noticed that halving the bitrate and screen size does give me a 50% smaller file that still looks nearly as good as the original on the Dingoo.

What other programs you reconmend?

Look around for a RMVB converter, and convert your videos for that format. They will play most nicely at any common rates you choose, i play my download TV Series without converting...

He's transcoding from xvid avi videos. He doesn't need a rmvb converter.

For programs, personally I use virtualdub. It can convert pretty much anything as long as you have the right codecs and plugins installed. It's mainly geared toward avi files. I don't know if you can render to the mp4 container. I'm sure there's some sort of plugin or work around out there.

So a Movie could be compressed from 700MB to 350-400MB (half) where as a South Park/Family Guy/Simpsons could be downgraded more without much notice... so i should get cartoons that are 200MB down to 75-100 MB each and still look watchable.
As I said earlier in the thread, I can get standard 22 minute cartoon episodes down to 50MB each, which look/sound fine on the Dingoo. 320x240 with 175kb video bitrate and 128kb audio bitrate.

The blocking/artifacting is due to the codec/compression, not the color depth of the Dingoo's display. You can see this with any divx/xvid/etc. Just watch a dark scene, or smoke, fog, or water. You will see what he is describing, even (especially) on a nice high def display.

Well i have messed about some more and found that 640X Video has more artifacts, than on a Samsung 3.5" Screen that plays Divx/Xvid, so when i play a 640X movie on that phone and then one with half the bitrate and 320X you can see the difference more between the two on the Phones Screen (it records Video at 720X480), but on the Dingoo the difference is not much at all especially with Cartoons.

So i think the slight trade off in quality, compared to getting near double the files on a card and only 2-3 minutes to re-encode means i will change videos to 320X Res and 400-500BR so i can get nearly double the videos on the card.

Did you try the bitrates I suggested for 22 minute cartoon episodes? Make it a two-pass encode as well.

Just done a South Park at 320 RES, 175BR, 128 Audio AAC in handbrake with 2 pass.

File Size was 50MB and video looks ok, you can now notice a difference more but hey it means that you can get 3.5X the episodes on the card.

a 4GB Card would take 22 X 175MB Cartoons so i may mess about with settings to get files to 75-80MB each, that should give better quality than the 175BR video but still small file size.

My aim would be to get 700MB Movies down to 350-400MB, or 200-250MB if Cartoon

45 Min TV down from 350 to 175MB-200MB

And Cartoons down from 175MB to 75-100MB

That should do the trick then......

So i can take 2X 4GB Cards and 2X 8GB and stock them up for Movies/TV and Games so i would have plenty to keep me busy!


EDIT.....

Just used Handbrake 320/350 BR/128 AAC and file is 75MB and looks better than the 50MB and cant tell difference from the 400 and 500BR ones i made.

So i guess for Cartoons a 350BR with 128 Audio is the best overall setting i got so far, for Movies/TV i may stick with 450BR.

Cheers for Help Jesse ;)

Yeah 175/128 is acceptable to me, and it's nice and even with 50MB per 22 minute episode. I pick out my 10 favorite episodes for each series (20 if they're 11 minute episodes). Get two cartoon shows per GB. And I got one 16 GB card with 8GB left for shows, and another 8 GB card that I'll probably be using for the same thing eventually. So far I've done it for Rocko's Modern Life, Freakazoid, and Home Movies. Johnny Bravo is next. ;) I also have a handful of live action shows. I hope I don't have to make them too much bigger to make them acceptable. If I have to, I'll just use all the space for my fav cartoons ;).

By the way, you are cutting out the end credits and other useless stuff yeah?

Also, you may want to try something even lower for the audio bitrate, especially with aac and if you are only going to use them on the Dingoo. Try 112kb and see if you can tell the difference and go from there.
