If you want to slow it to 24fps, you can slow the audio down by encoding it like this:

ffmpeg -loglevel error -stats -n -i “The Wrong Trousers HD v2.mkv” -vn -sn -af asetrate=46080,aresample=48000 -c:a aac -b:a 192k -vbr 5 “The Wrong Trousers HD v2.mka”

And just remux it with the video in mkvtoolnix, de-selecting the original audio, and setting the video frame rate to 24fps.

I’m not well versed in ffmpeg, does this operation keep the correct audio pitch? I assume you’re posting this for the benefit of those who want to keep their file BD-compliant.

Pitch is lower.
I think the slowed down audio pitch sounds closer to what I remember from the VHS I used to watch.

The main part of it is this:

-af asetrate=46080,aresample=48000

It slows it down to 46080Hz rate, and then resamples it to 48000Hz.

This encodes to aac 192k:

-c:a aac -b:a 192k -vbr 5

If you’re from the US, your VHS would have been pitched lower of course. I didn’t know I was watching it with the wrong pitch until I made this thread and the correct speed became a point of discussion.

If you’re doing 23.976fps (24000/1001) instead of 24fps, the rate would be 48000*960/1001

-af asetrate=48000*960/1001,aresample=48000

which works out to 46033.966, instead of 46080

The 1995 CBS/FOX VHS releases have the correct pitch audio, as well as the 2001 Warner/BBC DVD (don’t know if that release has the altered audio since it was released after 2000; we actually rented that DVD from Netflix in 2006 back when they were doing DVDs by mail). I’m not sure why the CBS/FOX DVD version has AGDO and TWT running at 24 and ACS at 25, why couldn’t they do pulldown on AGDO and TWT like ACS?

After ripping my 1999 DVD, AGDO and TWT run at 23.976, but ACS plays at the original 25 fps (even though it’s an NTSC release, 720x480, NOT 720x576). Luckily I grew up with the 2001 Warner DVD back then and remembered the pitch it was. After trying to watch W&G years later, the audio didn’t sound right until more than a year ago I found out that Aardman shot the films and did post at 25fps instead of the standard 24fps.

Honestly, if they really wanted to go 24fps, at least keep the audio the same. It’s just like 24fps get sped up for PAL regions at 25fps and the film audio is sped up, except it’s the reverse. We’re watching the film at an incorrect speed!

Interesting that the '95 VHS has the correct pitch. I wonder why more care wasn’t taken in later releases.

By the way, I’m working on A Grand Day Out now.

Is it possible, though? If I remember correctly, whenever a PAL (25p or 25i) source is converted to NTSC (24p with pulldown to 30p or 30i), most companies opt to convert the 25 frame/field-per-second source to an interlaced format (the aforementioned 30i), even if it was shot progressive (i.e. on film). In most instances of this method, the pitch of the original source is kept intact; could converting a progressive PAL (25p) source to progressive NTSC (23.976/24p) bring similar (if not completely identical) results? Many of the posts on this thread suggest that most U.S. home video releases of the “Wallace & Gromit” shorts present each short converted incorrectly.

(Oh, and one more thing: don’t you actually mean 640x480? The video of an NTSC DVD is indeed stored at 720x480, but is scaled to either 640x480 (4:3) or 853x480 (16:9))

A Grand Day Out is now up, speed corrected to 25fps, with speed/pitch corrected DVD audio and Blu-ray commentary. 3.27GB MKV.

I may do A Close Shave as well, but if I do I’ve decided to leave it in SD because of the cropped Blu-ray.

In my opinion, the 1.66:1 framing feels way too tight in many scenes. The crop isn’t even applied consistently, leading me to believe it may not have been intended to be masked.

It’s definitively quite tight. I had always assumed it was one of those deals where it’s framed for academy ratio and protected for 1.66:1, but the fact that you say the crop changes throughout challenges that idea. If that’s the case, why release the other two in their original ratio and crop this one? Very strange.

I’m totally up for the a 4:3 version at PAL speed. Maybe you could use ColorMatch to make it closer resemble the bluray (which has better colors).

Really? Those matted screenshots sure do show more horizontal picture info than the open matte screenshots…

Their point is that the opening title and subsequent crop are different, which would not be the case if the film was intended to be matted to 1.66:1. The 2nd crop has that off center crop reminiscent of how they screwed up Seinfeld and some other shows shot originally for 4:3. The extra image on the left would be matted out when adding the soundtrack to the final print.

Can, I ask what was different in the DVD Audio of “A Grand Day Out?” compared to the Bluray Audio?

The BD audio doesn’t have major changes like The Wrong Trousers, but it sounds like it might be a different mix. For example, when Wallace is drawing the ship with him and Gromit inside, Wallace is mumbling to himself in the BD track, but he isn’t making any sounds on the DVD that I can hear.

Thanks for explaining.

According to the very next post, Prime does not. I hope someone can confirm itunes though.

My bad, sorry for not reading the whole thing.
