The upload window for the WACV conference/Workshop papers will be Nov 19, 8am MST – Nov 23, 9am MST.
You will submit a video (formatted as below) For the main conference , your file name is $PAPERID-wacv.mp4 where $PAPERID is your unique WACV paper id (from CMT submission). There is no $ in the filename, $PAPERID is a variable to be expanded. For example, for WACV paper ID #12, please use 12-wacv.mp4 as the file name for the main conference video, and so on. No leading zeros.
Main Conference papers should submit one 4:55 minute (4 minutes 55 seconds) video file and one up to 48 (high)”x96″ (wide) landscape poster file in pdf format:
- Main conference papers should be 4:55 minutes (295 seconds or less) If it is longer it will be truncated. Note powerpoint cannot directly format that large, you can do 24×48 in powerpoint then scale by 200% when outputting to pdf. This maintains your images/graphics quality.
Main-conference Keynote should submit one video file:
- With length as specified by the program chairs.
Workshop paper or Tutorial submit the same except the naming includes workshop prefix from the following table
VAQ: Video/Audio Quality in Computer Vision, full day HAD: Human Activity Detection in Multi-Camera, Continuous, Long-Duration Video, full day DNOW: Dealing With the Novelty in Open Worlds, full day MAP: Manipulation, Adversarial and Presentation Attacks in Biometrics, half day, morning EIA: Explainable & Interpretable Artificial Intelligence for Biometrics, half day, afternoon, DVPB: Demographic Variations in Performance of Biometrics and Related Technology, full day RWS: Real-World Surveillance: Applications and Challenges, full day HPIV: Hazard Perception in Intelligent Vehicles, full day CVWS: Computer Vision for Winter Sports, half day ACI: Applications of Computational Imaging, half day
The length of the workshop/tutorial videos will be defined by your workshop or tutorial organizer.
Please ensure your video follows all of the following guidelines before uploading.
Videos can be in only one format: MP4 video 1920x1080p in H264 compression. This will enable us to load all talks into the online system for remote presentations. Videos that do not fit this resolution /formatting will be discarded and the associated paper pulled from the proceedings. All videos MUST have narration or it will be disregarded. If you are presenting live, we’ll just turn off the sound. You may get someone else to do your voice-over. Human narration is preferred but text-to-speech (TTS), is allowed if it makes the video easier to understand. There are some bad TTS and some better ones. If your narration is bad, people are more likely to skip your video.
When presenting, introduce yourself. There will be no time allotted for “questions” during the video session. As usual, any projected Text/Math should use at least 24 point font (and ideally should be >32pt) as smaller fonts will not be readable on small mobile screens.
Video/Slide Presentation Formatting
Talk slides need to be converted to video.
The video should be no more than the allotted time. It should start with a title slide. The video MUST be named as in the upload page and should be a Mpeg4 with 1920×1080 resolution, with H264 encoding. (H264 is the default codec for many MP4 encoders, but not all). It should NOT be an AVI file or a MOV but proper MP4 — and you cannot just rename it to convert it). You should record your narration. You are free to use picture-in-a-picture.
You might use Youtube or FFMPEG to convert formats.
If you prepare your presentation using PowerPoint, you can time your slides and save the presentation as a WMV video directly from PowerPoint but must then convert to MP4, e.g. via Youtube or FFMPEG.
Alternatively, there are many free screen capture programs that directly produce proper MP4:
- VLC- (http://www.videolan.org/vlc/index.html)which works on all platforms.
- OBS- https://obsproject.com/
- Tinytake- (http://tinytake.com/) for Windows.
- For Mac there is the built-in QuickTime, which will need to be exported as MP4 because the QuickTime default is MOV).
- For Mac users using keynote
- Keynote now. Fabian Mentzer says You can do Play > Record Slideshow…, then record it. This seems to just record timestamps. But then you do File > Export to Movie, select “Slideshow Recording”, Custom resolution (1920×1080). This puts a H264-encoded video in an m4v, which can be turned into an mp4 with ffmpeg as below
If you have an mp4 file after your encoding you can upload that directly. If you only have video recorders producing other formats, e.g. avi or wmf , Youtube may be able to convert for you (upload then download) or convert using FFMPEG ( https://ffmpeg.org/
- ffmpeg -i source_video.avi -acodec aac -c:v libx264 -crf 16 -s 1920×1080 -t 5:00 -preset slow -s 1920×1080 PAPERNUMBER.mp4
- One can even use FFMPEG to create a video from slides, but screen recording is far easier.
- If using FFMPEG or other tools please make sure the frame rate is 30fps.
After upload, you will receive an email. If you upload a second time, it will simply overwrite your original file, so if you want to update the file just upload a second time. But please don’t upload again and again as it takes a lot of resources.
If you do not see an email after your submission, check your SPAM folder.
