I’ve been an apple user for years, and gradually get familiar with apple software and hardware’s characters. Though I still out line of buying an iPad from apple shop, but I can’t wait to fancy playing my DVD movies upon iPad. I know that I should get a converter or ripper or the stuff like this, and I know it well. As always, I consult google for a while and get Handbrake finally.

With the step-by-step tutorial above, I quit to conclude a how-to article about how to use Handbrake since I am a fresh too. Otherwise, I note something that not that favorable as I thought before.

1. I'm trying to recode a blue Ray rip that is in h.264 format. I have got this to work on a bunch of DVD rips but for some reason the sound and video are there but they are not overlapping, surely they also call this A/V out of Sync.
2. Handbrake will NOT be able to convert individual video files saved on a DVD-ROM.
3. I noticed that while encoding Alice in Wonderland (not a great movie) that my CPU was being totally used up by Handbrake. I am on a new MacBook (Snow Leopard 10.6).
And maybe these are not a big deal comparing with other software. But I still give a wish to the update of Handbrake or something that alternative to HB.

Quick summary and practical fixes for the three problems described (A/V sync on a Blu‑ray rip, “won’t convert individual files on a DVD‑ROM”, and very high CPU use). HandBrake is a solid transcode tool and can open most disc folders and common containers, but it does not defeat copy protection — encrypted discs often need a separate rip step first. (handbrake.fr)

A/V drift most commonly comes from timing/frame‑rate mismatches (variable frame rate, start timestamps, or container metadata). First inspect the source with MediaInfo to see frame‑rate mode and any audio delay metadata. If the source is VFR try a short test encode with “Same as source” (or force a known CFR) and toggle the Align A/V Start option; test a one‑minute range to iterate fast. If that fails, remuxing or re‑ripping the source often fixes mysterious offsets. (mediaarea.net)

If you need to nudge audio timing without re‑encoding, ffmpeg can remux and shift an audio stream (adjust the offset value until sync is correct). Example (remux, copy streams, delay audio by 0.5s):

ffmpeg -i input.mkv -itsoffset 0.5 -i input.mkv -map 0:v -map 1:a -c copy output.mkv

See ffmpeg docs for -itsoffset and stream mapping. (ffmpeg.org)

About DVDs/Blu‑rays and HandBrake: HandBrake will open VIDEO_TS/BDMV and many file types, but some AVCHD playlists or encrypted discs aren’t fully supported — for encrypted Blu‑rays it’s common to rip to an MKV first with MakeMKV, then transcode with HandBrake. That two‑step workflow preserves correct timestamps and audio tracks for HandBrake to work on. (handbrake.fr)

Finally, full CPU use during encoding is expected — HandBrake is CPU‑bound for most encodes. On modern macOS you can enable hardware acceleration to lower CPU load; on older systems (Snow Leopard era) there wasn’t much hardware offload so heavy CPU use is normal. Also, ’s Evom suggestion is a valid idea for simple conversions but Evom appears old/unmaintained; consider current ffmpeg tools or actively maintained GUIs if you want simpler drag‑and‑drop workflows. (handbrake.fr)

Actionable checklist: (1) run MediaInfo on the file, (2) if disc is encrypted rip with MakeMKV, (3) test short ranges in HandBrake and toggle Align A/V, (4) use ffmpeg -itsoffset to remux if needed, (5) use faster presets or hardware accel to reduce CPU.

Try Evom to recode video files, e.g FLV or AVI (XVid or DivX) to MP4

've found Handbrake to be the best for Ripping DVDs. It will use all of your CPU if it's spare. If you're doing other things, it'll fight for processor time, but will work fine with other apps.

Wow, I was looking for exactly this piece of software to help me, thanks for sharing.
