Export, Delivery, and Workflow flashcards for Video Editing

22 of 50 cards from the Export, Delivery, and Workflow deck — real questions with worked answers.

1. In video export settings, what is bitrate and what units is it typically measured in?

   Bitrate is the amount of data encoded per second of video, controlling file size and quality. It is typically measured in megabits per second ($\text{Mbps}$). Higher bitrate means higher quality and larger files.

2. What is the difference between CBR and VBR encoding?

   CBR (Constant Bitrate) keeps the same data rate throughout the video, giving predictable file sizes. VBR (Variable Bitrate) allocates more data to complex scenes and less to simple ones, producing better quality per megabyte. VBR 2-pass analyzes the video first, then encodes for the most efficient result.

3. What is the H.264 codec and why is it the most common delivery codec?

   H.264 (AVC) is a lossy compression codec that offers an excellent balance of quality, small file size, and near-universal playback compatibility across devices and platforms, making it the standard for web and client delivery.

4. How does H.265 (HEVC) compare to H.264?

   H.265 achieves roughly the same visual quality at about half the bitrate of H.264 (about $50\%$ smaller files), making it ideal for 4K/HDR delivery, but it requires more processing power to encode/decode and has less universal device compatibility.

5. What is the difference between a codec and a container (wrapper)?

   A codec (e.g., H.264, ProRes) is the algorithm that compresses/decompresses the video data. A container (e.g., .mp4, .mov, .mkv) is the file format that packages the encoded video, audio, and metadata together.

6. How do you estimate the file size of an export from its bitrate and duration?

   $$\text{File size (MB)} = \frac{\text{bitrate (Mbps)} \times \text{duration (s)}}{8}$$ Divide by 8 because there are 8 bits in a byte. Example: $10\ \text{Mbps} \times 60\ \text{s} \div 8 = 75\ \text{MB}$.

7. What resolution and aspect ratio should you export for YouTube versus TikTok/Instagram Reels?

   YouTube: horizontal $16{:}9$, typically $1920 \times 1080$ (HD) or $3840 \times 2160$ (4K). TikTok/Reels/Shorts: vertical $9{:}16$, typically $1080 \times 1920$. Instagram feed also supports square $1{:}1$ and portrait $4{:}5$.

8. Why is it recommended to upload to YouTube at a higher bitrate (or 4K) than the platform's playback bitrate?

   Platforms re-compress every upload. Uploading a higher-quality master gives their encoder better source material, so the final streamed version looks better. 4K uploads also get YouTube's higher-quality VP9/AV1 encoding even when watched at 1080p.

9. What are broadcast delivery specs likely to require that web delivery does not?

   Broadcast typically requires specific mezzanine codecs (e.g., ProRes 422 HQ or XDCAM), legal broadcast-safe levels (limited video range), loudness compliance (e.g., $-23\ \text{LUFS}$ EBU R128 or $-24\ \text{LKFS}$ ATSC A/85), specific frame rates, and closed caption files.

10. What is a mezzanine (intermediate) codec and give two examples?

    A mezzanine codec is a high-quality, lightly compressed intra-frame codec used for editing, archiving, and master files rather than final delivery. Examples: Apple ProRes (e.g., ProRes 422, 4444) and Avid DNxHD/DNxHR.

11. What is chroma subsampling, and what do 4:2:0, 4:2:2, and 4:4:4 mean?

    Chroma subsampling reduces color resolution relative to brightness to save data. $4{:}4{:}4$ keeps full color information; $4{:}2{:}2$ halves horizontal color resolution (common in pro/mezzanine codecs); $4{:}2{:}0$ quarters color information (standard for consumer delivery like H.264 web video).

12. What is batch rendering/exporting and what tool provides it in the Adobe ecosystem?

    Batch rendering queues multiple sequences or compositions to export automatically one after another (or in parallel) without manual intervention. Adobe Media Encoder provides this for Premiere Pro and After Effects, letting you queue many jobs with different presets.

13. What is background rendering and what is its main benefit?

    Background rendering exports or renders previews using spare system resources while you continue editing in the foreground (e.g., sending exports to Media Encoder, or DaVinci Resolve's background caching). The benefit is no downtime — you keep working during renders.

14. What is the difference between subtitles and closed captions?

    Subtitles transcribe or translate dialogue only, assuming the viewer can hear. Closed captions (CC) are for deaf/hard-of-hearing viewers and also describe non-speech audio like sound effects, music cues, and speaker identification. Closed captions can be toggled on/off; open captions are burned into the image.

15. What is an SRT file?

    SubRip Subtitle (.srt) is the most widely supported plain-text caption format. Each entry contains a sequence number, a timecode range (e.g., 00:00:01,000 --> 00:00:04,000), and the caption text. It carries no styling information.

16. How do open captions differ from closed captions, and when would you use open captions?

    Open captions are permanently burned into the video image and cannot be turned off; closed captions are a separate track/file the viewer can toggle. Use open captions for social media platforms where autoplay is muted and you want guaranteed styling, or where sidecar caption files aren't supported.

17. Why should you always review auto-transcription output before publishing captions?

    Speech-to-text engines make errors with proper nouns, technical jargon, accents, homophones, overlapping speakers, and punctuation. Accuracy is typically $85\text{–}95\%$, so human review is required for correct spelling, speaker labels, timing, and compliance with accessibility standards.

18. Name two ways auto-transcription is used in modern editing workflows beyond captions.

    1) Text-based editing: editing the video by cutting words in the transcript (e.g., Premiere Pro Text-Based Editing, Descript). 2) Searchability and logging: finding moments in footage by searching dialogue, plus generating searchable metadata, show notes, and translations.

19. What is a common caption style guideline for line length and lines per caption?

    Keep captions to a maximum of about $32\text{–}42$ characters per line and no more than 2 lines on screen at once, displayed long enough to read (roughly $1\text{–}7$ seconds), synchronized with the audio.

20. What are frame-accurate review platforms, and name two examples?

    They are cloud tools where clients leave time-stamped, frame-accurate comments and annotations directly on an uploaded cut, replacing vague email feedback. Examples: Frame.io (integrated with Premiere Pro) and Wipster; Vimeo Review is another option.

21. What is a structured revision-round system in client work and why is it used?

    The contract specifies a fixed number of revision rounds (commonly $2\text{–}3$) where the client consolidates all feedback into one list per round; extra rounds bill at an hourly or per-round rate. It prevents endless revisions and scope creep while keeping feedback organized.

22. What is the recommended way to handle vague client feedback like 'make it pop'?

    Ask clarifying questions to translate it into actionable specifics (Which section? Pacing, color, music, graphics?), reference examples, and confirm the concrete change in writing before editing — this prevents wasted revision cycles.
