Hello, I've been reading the forums but only lurking since my A7HT arrived a week or so ago. I too would like this thread to become a wiki entry but it seems to have grown cold.
One of my primary uses for the A7HT was as a movie viewer (for trips, etc), so I wanted to fit as many titles on my 8G uSD card as possible while keeping "adequate" (not necessarily great) quality (since the 7" screen is only 800x480).HandBrake
seems to be the recommended choice after the DVD contents were copied to disk. I thought I read somewhere that either the Regular/Normal
preset or the Apple/Iphone
preset would work on the A7HT (both create an H.264 MP4/M4V
file), so I first tried the Regular/Normal
preset. After experiencing/fixing the "weightp" problem (thank you very
much for identifying this, v_c), I found that, although the resulting .m4v files seemed
to play fine, if I used the slider (or a bookmark) to reposition the video, the audio went out of sync and the video became jumpy.
So then I tried the Apple/Iphone
preset and now both viewing and repositioning seem to work fine. My subsequent tweaking to this preset (now obviously saved under a different name) was to specify
- "Anamorphic=Strict" (Picture tab)
- "Constant Quality=50%" (Video tab)
- "DRC=2" (Audio tab)
- ":weightp=0" at the end of the options (Advanced tab)
Note: DRC is Dynamic Range Compression and seems
to help the sound, but HandBrake 0.9.4 does not save the value with the preset, so it must be respecified every time the preset is loaded (if you want to use it).
I believe "Strict" tells HandBrake to create an anamorphic (smaller) result file, so the "Screen Display Format" button (diagonal with two arrowheads) must be pressed once
after starting the video to expand it back to full-screen.
One more thing - if the source video is "wider" than 16:9, HandBrake will try to crop the top and bottom of the video. Although the resulting file plays fine in VLC Media Player, the A7HT player gets confused and vertically stretches the video back to 16:9. Therefore, if you notice (on the Picture tab) that HandBrake has cropped more than one or two pixels from the top/bottom, select "Custom" and set the Top/Bottom crop back to zeros.
Ok. I now have a bunch of .m4v files copied to my 8G uSD card that play quite well but require only about 300-400 MB per hour of video (MediaInfo says the videos play at 500-600 Kbps).
As an aside question to you all, since even a 2000 kb/s video requires less than 1 MB/sec, would a Class-2 uSD card (2 MB/sec?) play these videos well? It would certainly cost less than my current Class-6 card...
