===== context=====
dit document gives a few tips on how to troubleshoot problems with Handbrake.

===== check the logs=====
  * button: **Activity Log**
  * you can browse to the log directory of previous activity
  * search for the string "duration" and compare that value with the length of your ripped file. It should be 1:1
  * check for any entries that start with ''sync'' for actual ripping (as opposed to ''read'': reading the dvd) <code>[19:25:41] sync: "Chapter 8" (8) at frame 35127 time 126461520
[19:26:14] sync: "Chapter 9" (9) at frame 39581 time 142495920</code>
  * you can see at what point the ripping failed:<code>[16:23:22] sync: "Chapter 4" (4) at frame 14913 time 53683200^M
[16:26:21] sync: "Chapter 5" (5) at frame 27479 time 98920800^M
[16:29:13] sync: "Chapter 6" (6) at frame 38866 time 139914000^M
dvdnav: Read Error, Error reading from DVD.^M
[16:29:35] reader: done. 1 scr changes^M
[16:29:36] work: average encoding speed for job is 63.288017 fps^M
</code>
  * **chapters scan** should match **chapters synced**: {{ :handbrake:2026-01-18_17_48_01-queue.png?400 |}} {{ :handbrake:2026-01-18_17_47_33-queue.png?400 |}}

===== check your physical media=====
  - start by cleaning your media
  - observe if reading the DVD in Handbrake is fluent.
    - If it takes longer than usual to read, chances are ripping will be problematic at some point{{ :handbrake:handbrakereadingdvdtakingtoolong.png?800 |}}
    - if the DVD-writer makes an unusual sound while reading, you'll probably have problems with the rip later on. 
===== try ripping again =====

  - rip the episode **separately** (not part of a queue!). That has helped me on more than one occasion. \\ It seems that ripping bails out easier when queued than when ripping separately ...
  - example: 
    - Medium S2 D3-4.mkv 04-28-2020 12-27-55.txt
    - Medium S2 D3-4.mkv 04-28-2020 14-03-15.txt
  - check the logs: if the rip fails at the same point, it is most likely the physical media. 
    - Medium S2 D4-5.mkv 04-28-2020 10-46-17.txt
===== restart handbrake completely =====
  * it's a bit of a drag, but it helps sometimes.  
===== try ripping with alternative tool =====
  * [[https://www.makemkv.com/|makemkv]] is a good candidate, but usually the ripping bails out at the same point...
===== play the episode in VLC =====
  * open the ripped file in VLC and see at what point in time it fails
  * open the __same episode__ from the original dvd and see if it fails/hangs at the same point. 
  * If so, it is clearly a dvd (disk) issue.  In that case, you could get a copy of the public library and try ripping that. 

===== known error messages =====
