Hello,
I have to convert a PowerPoint slide show video into another frame rate, for upload to facebook.
The conversions with Handbrake are great, but not consistent, it is only by chance that the video is flawless. Most come with some minor defects, as can be seen in the video below:
What advanced settings of Handbrake, in the commad line or on the Advanced tab, are to be selected to convert a slide show video flawlessly, without these defects?
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Have you tried convert with something else? Like xmedia recode?

First, there are a number of settings for getting optimal slideshows out of PPT. What are you using? Also highly depends on which PPT version you're using...
Next, is this a picture or video export? Or is it a screen recording? Lots depends on whether you need animations, filesize requirements, etc.
Next, what intermediate steps HAVE you taken (or were intending to take)?
If done right, your export/capture framerate will already match the framerate you'd want for YT.
Any MediaInfo data? Clip uploads?...

The video was initially intended for facebook and there a conversion is needed prior to uploading because the slides suffer heavy distortions, then Youtube has as well "come into play". You are right, it doesn't need to be converted for an upload to Ytb. I will edit the post.
Thanks. This one seems to have no option for changing the frame rate, which I need, as described above. -
Thank you.
I've been converting PPT 2013 created 1920x1080 videos into various versions of x264 encodes with Handbrake. The settings I've been trying were 60 fps CFR, x264 Slow/Slower Film/Animation/Still Image/Grain/None High 4.1-5.1 and RF 18-16
All of the encodes contained 1 to 3 defects as depicted on the provided Vimeo video. By chance a faultless encode was produced and I want to figure out if certain command line or Advanced tab options could effect an essential improvement of a x264 encode.
What I pleasantly discovered is that the x265 codec (RF 14 admittedly on 'Slower') encodes robustly and consistently without a single flaw. I rely upon that and convert it back to x264 for Youtube, but still it'd be interesting to know if certain Handbrake options tweaking have the power to deliver consistency within the x264 framework.
The MediaInfo specs of the ppt video are included below:
Code:Complete name : D:\pp - 17.mp4 Format : MPEG-4 Format profile : Base Media / Version 2 Codec ID : mp42 (mp41/isom) File size : 496 MiB Duration : 6mn 24s Overall bit rate : 10.8 Mbps Encoded date : UTC 2016-04-04 13:10:02 Tagged date : UTC 2016-04-04 13:10:02 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : Baseline@L4 Format settings, CABAC : No Format settings, ReFrames : 2 frames Format settings, GOP : M=1, N=30 Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 6mn 24s Bit rate : 10.8 Mbps Width : 1 440 pixels Height : 1 080 pixels Display aspect ratio : 4:3 Frame rate mode : Constant Frame rate : 30.303 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.229 Stream size : 496 MiB (100%) Encoded date : UTC 2016-04-04 13:10:02 Tagged date : UTC 2016-04-04 13:10:02 mdhd_Duration : 384648
