How to convert from 60fps to 25fps to get continuous video?

[poisondeathray]

Okay, you also mentioned you can check the Frame amount in Mediainfo. Where is that written on the info sheet? It doesn't list the frame amount for me.

I don't understand "frame amount" ? Clarify what you mean ?

The number of frames in the file.



By the way, regarding this selection issue, what camcorder would you recommend then under 1000$? I told you I would only have 1000$ for it, no more. It should have a line in mic at least.

[poisondeathray]

you can use view=>text , debug=>advanced mode

But mediainfo isn't reliable to determine frame count . It doesn't actually count them (like an indexing program). It just looks at the duration and reported fps to calculate

duration time in seconds x frames/second = # frames

for example it reports 2912 frames on the yamb re-wrapped file, but incorrectly 5824 (double) on the native file because the reported fps is incorrect


I don't know what to recommend, have a look at reviews or start a new thread. All I know is the clips you have posted were soft (that's the first thing I thought of when seeing the foliage clip) compared to typical AVCHD camcorders

It's only reported for some files. It will be in the video stream section if it's there.

Yes, but actually on HDTV it is not an issue. There, the image is very sharp.

The point is , a shot like that will look much sharper with other camcorder, mainly because of better compression and higher bitrates. Low bitrate AVCHD for aquisition has this characteristic blurry, mushy look, as fine details are eroded away. I'm 100% sure about this compression issue.

Okay guys, I wrote the outcome to DVD. It is good! It is constant.

But the sound still seems a bit crappy for me. Are you sure this Yamb does not confuse anything? When I check the original mp4, mediainfo says: Normal bitrate: 128, Max: 192. For the Yamb output mp4: Bitrate:127, Max: 137. Why is this? Maybe there is not even a bitrate more than 137 in the original sound actually in the variable bitrate sound, that's why the 137 max?

[jagabo]

MediaInfo is just reading what the header says. What the header says may have no bearing on what's in the file. I suspect YAMB actually examined the data as it muxed and saw that the max bitrate actually used in the audio stream was 137 kbps. On the other hand, it may have simply used a different time window over which to take the measurement.

[Bencuri]

Okay. Well it is not that a big problem anyway.

[poisondeathray]

To prove it to yourself, you don't have to use yamb for the audio. Use the audio from original file. It has to be re-encoded anyway (AAC isn't compatible with DVD-video) and will sound the same as if you use the audio from yamb if you use the same encoding settings. Examine the audio in an audio editor. Yamb does not have the ability to re-encode. When most people do real authoring, they use separate audio & video anyway

What bitrate are you re-encoding the audio for the DVD? Try something higher to minimize the quality loss. That's the step where you use quality

[Bencuri]

Actually I was not exact now.

The final mpeg was from the m2v and an ac3 created by Audacity. That had no relation to what Yamb did, it was converted from a Wav. It is 192 kbps constant ac3.

But the sound really seemed a little poor. Maybe I should try higher bitrate for the ac3? I guess it would have no use, right? Or some other setting in TMPEnc?

By the way, at Creation in Yamb, I could just add the video segment and create an mp4 without the audio part. Later in HCGUI, the sound will be separated again, so why adding the sound again in Yam, then. Hmm?

[jagabo]

I would use 256 kbps for 2.0 AC3 audio.

Correct, you don't need to add the audio in yamb. That step was only to re-write the framerate information

You can try cleaning up the audio a little bit as well (there is interference). If original audio has problems, then re-encoding it will only make things worse

I think I will skip that now, I have no clue how to deinterfere that. The sound can be accepted anyway, it is not that very bad.

An update, by the way: when I play the DVD files on cumputer, there are sometimes small jumps at fast movements. When I play the DVD with player on my analogue TV, there is no. I guess this is because of the interlacing, right?

And regarding settings: If I want the picture in 4:3 for the DVD, I just need to set this in HcGUI, or in the script I also have to modify this line:

LanczosResize(720,576) ?

Do you want to pan and scan, or letterbox?

Remember the discussion about bob deinterlacing, and how wmp depends on how you have your directshow filters setup? Most PC media players will single rate deinterlace so you get 25p instead of 50p

I suggested using VLC and forcing bob or yadif 2x to preview, so it looks like it would be more representative of how it looks on DVD player

And you're watching 25 or 50 Hz material on a 60 Hz computer monitor. And the motion interpolation is never perfect so you will sometimes see blends and jumps.

[poisondeathray]

Why does he have a 60Hz monitor?

[jagabo]

I'm guessing his computer monitor is 60 Hz.

[poisondeathray]

I'm guessing his computer monitor is 60 Hz.

Don't tell me... it's a Sanyo monitor and they don' t make 50Hz PAL monitor either like his camcorder ??

All of my 3 laptops have 60hz setup. You cannot change this value. These are all EU types, I purchased these locally. So this is not my fault. You can only change to 50HZ when you plug the laptops to HDTV.

[Bencuri]

Guys, there is problem again. It seems this case never ends. Yamb, this time. 2 of my mp4s from this concert are not extracted. During the process Yamb stops and reports that MP4BOX stopped functioning, and the extractions stops.

The same happens if I install the 1.6 Yamb, not the beta. Both freezes.

Seriously?? Wow! Is this common thing for EU type laptops in a 50Hz region ????? Even UK laptops?

[jagabo]

I thought most computers with LCD monitors in PAL countries ran at 60 Hz.

[poisondeathray]

Wow I just assumed they ran at 50Hz.

Why would their LCD HDTV sets and other display devices run 50Hz , but only computer monitors and laptops run at 60Hz? It doesn't make sense ????

I think for laptop that is the standard. On my HDTV, you can choose computer HDMI input, that function is 60hz by default, no other value can be selected. On usual HDMI input, you can adjust, and then the laptop also allows to choose 50hz. But on the laptop lcd, only 60hz can be set. So this is the standard.

[poisondeathray]

What about standalone LCD computer monitor? or is this just laptop display ?

[Bencuri]

Guys, back to this brainkiller project. There are big problems again!

Yamb doesn't process 2 of my mp4's, it stops, and writes: MP4box stopped working.

HCGUI is crazy again. It acknowledges the correct frame amount, time ok, set to All frames for encoding. Yet, the outcome is not the full lenght movie. Again, from the 5:50 movie, it only converts 4:33.

Here is the video with Yamb problem, HcGUI setting, script. You can see all is how you suggested, but Yamb stops, and HcGUI output shorter file.

Log is attached!

[poisondeathray]

maybe they are damaged?

or you can try the directshowsource method , but might have to use the trim

if you cannot fix the framerate with yamb or other method, don't even bother going farther with hcenc, you already know it's going to be messed up

if they aren't too large, I can offer to look at one, but I won't download a huge file

[Bencuri]

Damaged? Not other program reports error!

They are very large, 2,2 GB the 2.
