nexus one video conversion with handbrake

---

Hi,
Anyone tried using handbrake to do video conversion to mp4 h.264? I'm using 0.9.4 and not having much luck. All i get out is the audio. I can convert to 480x320 resolution on Videora but trying to get 800x480, or something close to that resolution. So i have this video i want to convert and in Handbrake i used the native 720x304 screen size at 24fps. I think i tried 29.997fps too. I am wondering if the bitrate needs to be some specific multiple like 768kbps or 1.5Mbps. Is there a configuration that will work with the Nexus? Thanks in advance.

[update] so i stumbled upon this link that may or may not help.

i will try it out tonight and let you folks know.

[update2] hey what do you know, it works! i used the "iPhone & iPod Touch" preset and it looked pretty good. exciting! need to experiment with more videos. follow the instructions in the link and make sure you adjust the width appropriately. definitely don't try a resolution that is over the source resolution, that's just wasteful! hehe

I know the physical sizes of the iPod/iTouch are about the same, but isn't the resolution 2 times less?

Nexus One Resolution: 800 x 400 = 320,000 Pixels

Iphone Resolution: 480 x 320 = 153,600 Pixels

2.08 times less?

It would seem you are not getting near the resolution the phone is capable of.

my problem was Handbrake was saving everything as .m4a. Change your extension to .mp4 if you haven't already done so.

somehow that particular preset works, you can adjust the output resolution in the first tab. from what i'm seeing it seems like it's working. i will use a media tool to check the resultant file's resolution tonight. good point though.

The Windows Mobile part of the forum has a great application that has thus far worked great for me.

I actually just got handbrake set up doing video conversions for the Nexus, but it's at home. If I remember correctly, I used the iPod settings, then changed a couple of values (namely setting the width to 800 by default and letting it keep aspect ratio) and set a preset. Looks fantastic on the Nexus, I'll try to see if I can export the preset somehow when I get home and send it your way.

Looking forward to this

try format factory... it has a preset for the N1

Handbrake is great , has alot of options, as usual it is only good if you know what you are doing, so we need a preset that WORKS.
right now I'm testing HD Encoder by projection, runnig it on Ubuntu usin Wine 1.2 Beta , well it has ceashed ... will test more.
The good thing is you have just 3 options ... so it's easy to use

Rats, I can't seem to find a way to export a preset, so I'll just try to type out what I set. I know I started with the iPod preset:

On Picture, I have Width = 800, then click "Keep Aspect Ratio" and let it populate height. Anamorphic set to "None", Cropping set to "Automatic".

On Video Filters, everything is set to Off and unchecked.

On Video, Video Codec is H.264 (x264), Framerate is "Same as source", Avg. Bitrate is checked with the value of "1500"

On Audio, the one track is set as Source: Automatic, Audio Codec: AAC (faac), Mixdown: Stereo, Samplerate: 48, Bitrate: 128, DRC: 0.0.

Nothing special for Subtitles or Chapters

Advanced I've got:
Reference Frames: 1
B-Frames: 0
Motion Estimation Method: Uneven Multi-Hexagon
Subpixel Motion Estimation: 6
Motion Estimation Range: Default (16)
Analysis: All
8x8 DCT: Unchecked
CABAC Entropy Coding: Unchecked
Psychovisual Rate Distortion: Greyed, all the way left.
No Fast-P-Skip: Checked
No DCT-Decimate: Unchecked
Deblocking: Both on Default.

Hope that helps!
