iPod touch Video on Touch: Thoughts on Handbrake

Once again - to deinterlace or not?

I'm curious what the time/benefit ratio is.

I havent a clue what that means

but why dont you try a smlle file size of 5 mins and do one with deinterlace and one without and you should get your answer

i have now taken handbrake off my pc and gonna stick with decrypter and 3gp and quicktime to do my dvds

so i cant do a trial and error anymore but let me know if you try it and how it works out , does it give you a better quailty play back or not

i have a feeling the deinterlace might be for tv apple outputs but cant possibley be sure

Well that depends on whether the source material is interlaced, assuming that it is:

time = not much extra if using fast or slow deinterlace, don't use slower or slowest.

benefit = no jagged lines when displaying motion. will still get a shadow effect though caused by displaying two merged frames at a time.

To me the benefit far outweighs any cost. But don't use it on non-interlaced material, like movies, as it will stuff them up a bit.

Cheers, Ed.

Thanks. Are you running Intel or PPC? I have a PPC and H.264 takes forever as it is. If it's not much extra time on that, I'd do it...
 
I am running a PowerBook G4 w/ 1.25 Ghz

I used mac the ripper to burn a dvd on to my hardrive (which only took about 40 min) and now I am trying to convert it in handbrake. I have it set the mpeg 4, 1000 bitrate, and 2 pass encoding. Handbrake is saying it is going to take 6 hours to decode a 2 1/2 hour movie! This cant be right... My new ipod touch is arriving today and I really need help. Thanks.

You do not need the bitrate set that high. I use 600 to 660. Single pass is fine and in the popup menu on the right choose the mpeg-4 video/ACC Audio. I bet ti takes only 50-60 minutes to grind out.

Try it and watch the video on your Touch. Use your other copy for larger screens.

Even with those setting it is still saying 6 hours...
 
I'm sorry, just read the first part - G4 1.25ghz. That's your problem.

How much RAM you got? Video is a real HOG on the entire system.
 
so, I should expect it to take 6 hours with my current G4? How much RAM is needed?

I guess an upgrade my have to come sooner than I expected...

I just did Transformers - a 2 hr 20 min movie. It took a 2.1 ghz PPC G5 with 2.5 gig of RAM 57 minutes and I thought that was long.

Addressing various points...

I have a 1.42 G4/1 Gig RAM. It does Mpeg-4 (NOT H.264!) encodes in near-real time, i.e., about a minute for every minute of video. Your setup should be fairly similar.

-I would stick to 1000kbps if you're doing Mpeg-4. H.264 has better quality at lower bitrates - but takes forever to encode on a G4. Bumping up to 1000kbps yields acceptable (to me) Mpeg-4s - although the file sizes are bigger.

-2-pass encoding will always take longer (as much as twice, natch) than 1-pass.

-I actually don't know if encoding times correspond to bitrates, or just to the codec you use. Thus, not sure if 600kbps Mpeg-4 is faster than 1000kbps Mpeg-4. My guess is perhaps not; Mpeg-4 is about the same at any setting, and faster (on a PPC) than H.264 at any setting.

Adding all that up: 6 hours may be about right given your settings. Mpeg-4 is about real-time, maybe a little slower, so 3 hours for a (1-pass) 2.5 hr movie is acceptable. 2-pass = twice as long = 6 hours.

My advice: try to stick to 1-pass, or see if you can check the turbo 1st-pass box (this may not be an option for Mpeg-4, though).

I don't know if more RAM will help. I think encode times are a processor-specific thing. Also, the H.264 encoder in Handbrake is poorly optimized for PPC (I've heard), which makes it take so much longer.

Elgato sells a USB-pluggable H.264 hardware encoder doodad for $99. May work better than a computer upgrade.

And - nice to see a non-hacking thread survive!
 
Further updates:

To Deinterlace or Not? - tried this with an episode of Venture Bros., and Handbrake's "fast deinterlace" option actually made it look worse - smooth lines became jagged in still scenes. I don't want to try a better/slower deinterlace option on a PPC, so will probably stick to interlaced.

Elgato's Turbo.264 - on reading many, many reviews & impressions of this here & elsewhere, it sounds like this offers better speed but at a noticeable hit to quality. It doesn't work with Handbrake, and it's unclear how many options for bitrate, screen size, etc. the proprietary software allows in its latest version. So - spend $100 for this and have worse-looking videos, or just let the Mac run on Handbrake overnight? I vote the latter.
 
I just convert everything with quicktime

@152Kbps H.264 [2 Pass] & 64Kbps AAC and I get about 22 min of video at under 25MB and it looks fine to me. A little but blurry at certain times, but totally watchable, and not to mention I got all four seasons of Futurama at under 1.75GB

Yes, I use my Vista machine for rendering, my Mac laptop just isn't fast enough [Still love it more though...]

All I can say is...invest the extra $100 for a 16GB. Or not. I have 13 episodes of a 22-min. show, 26 episodes of a 25-min. show, one or two 45-min. shows, and two 1-hour shows -- all at just under 8GB, @ 600kbps or better. That's close to 20 hours of video, more than you can watch on 3 full charges, at good quality. I can't imagine why you'd need to cram so much more in, and at that quality hit to boot.
 
just did Transformers last nite, took about an hour maybe less with the two pass setting. I was surprised how fast it went, this was the first rip with my new ram, I now have 4gb.

the only issue I have is that even though I picked the preset for iPod Touch, the text in the movie is truncated, so when the scene that starts out in Washington DC only shows 'hington DC' on the Touch.

Try double tapping on the screen to see if that shrinks the video so that it isn't longer than the screen.
 
Handbrake 0.9.1 is out, looks to have a spiffier interface along with bug fixes (won't crash anymore when you change image dimensions too much!)
 
I can't seem to change the dimensions of the output settings in Handbrake i.e. it won't let me key anything into the input fields. Am I being totally dumb here?
 
iPhone 4 / iPod Touch - Handbrake 1-pass vs 2-pass

Having found this thread I've done some of my own tests that may help. Using Handbrake I encoded using the 4 main methods mainly for iPhone 4 viewing. I took any defaults that were given by Handbrake.

Format: MP4
Video Codec: H.264
Framerate: 29.97 (nearest to iPhone 4 max frame rate)
Picture Output: 720x384 (to match maximum width supported by iPhone 4)

The four encodings I made were:
1. 1-pass, average bit rate 460 kbps (521MB file produced)
2. 2-pass, average bit rate 460 kbps (526MB file produced)
3. 2-pass turbo, average bit rate 460 (526MB file produced)
4. Constant Quality (1.4GB file produced)

I downloaded to my iPhone and then viewed on the retina display and also on a 40inch LCD TV using the Apple AV connector.

Assessment for iPhone viewing:
a) '1-pass' showed visible pixelation and blocking
b) '2-pass' had almost no pixelation and no visble blocking
c) '2-pass turbo' and '2-pass' appeared identical
d) 'Constant quality' gave a very small improvement on 2-pass and 2pass turbo

Assessment for TV viewing:
a) Only 'Constant quality' looked good and approached DVD quality

Conclusion:
- '2-pass' or '2-pass turbo' are worthwhile settings for iPhone 4 viewing
- For iPhone 4 viewing I'll be using the '2-pass turbo' setting
- For TV output I'd use 'Constant Quality' but seldom do this so the extra space taken is not worth it for me.

Hope this helps.
