Select input and delivery first, don’t ask who is first
Let’s talk about the conclusion first: no software can be directly called the best without the task. When you only have one idea, watch text-to-video first; when you already have characters, products or key visuals, watch image-to-video first; when you need to deliver a finished film with subtitles, sound and multiple shots, you also need to take into account your editing capabilities.
When choosing video software, don’t just look at whether it can create a stunning five seconds, but look at whether it can manage the twenty shots you need.
This is also the reason why many trials end up disappointing: the display page shows you a good shot, but the actual task to be delivered is a complete video. In between there are film selection, redoing, sorting, cropping, dubbing, subtitles and exporting.
Text-to-video, image-to-video, and editing solve three different jobs
text-to-video is suitable for finding images from scratch. You describe the subject, action, environment, lighting, and shots, and the software creates a video clip based on that. It has a high degree of freedom and is suitable for atmospheric shots, concept films and creative exploration without fixed characters; the price is that the consistency between character looks, product details and multiple shots is more difficult to control.
image-to-video uses a picture as a starting point. Who the characters are, what the products look like, the composition and tone are already there, and the text is mainly responsible for the action and shots. It’s better suited to animate posters, showcase products, and continue existing visuals, but bad touches, typos, and perspective issues in the original image may also be brought into the video.
- There is no fixed picture, so I want to find a creative direction first: text-to-video.
- Characters, products or visual style must be preserved: image-to-video.
- To turn multiple clips into publishable content: In addition to the generation tools, look at the timeline, subtitles, audio, and export.
Runway: suitable for turning the generation process into a set of workflows
Runway currently puts Custom, Apps, Agents and Workflows in the same authoring system. Custom is suitable for controlling input and settings by yourself, Agent can plan and combine multiple shots through dialogue, and Workflows uses nodes to connect repeated steps. It is more suitable for people who are willing to repeatedly generate and manage versions, and gradually build up the video production process.
Runway's official introductory instructions support both text-to-video and image-to-video; the official long video guide also clearly states that longer content is usually composed of short clips and then combined through editing software. In other words, its advantage is not to "complete everything at once", but to provide a more complete generation and iteration workflow.
A full workflow isn't necessarily important if you only do a simple shot once in a while; it's more valuable if you're managing reference images, multiple versions, and multiple shots.
Firefly: For those already using the Adobe editing pipeline
Adobe Firefly can currently make videos from text as well as pictures, and provides settings such as frame, lens angle, angle, and movement. Once you've finished your clip, you can continue to open the Firefly video editor, or go into the Premiere desktop software.
This route is best for people who already work with footage in Adobe: the resulting shot is not an end point, but a continuation into a familiar editing environment. It should be noted that you can choose Adobe or partner models in Firefly. Different models support different settings, point consumption, and results. "Using the Firefly interface" cannot be equated with "always using the same model."
Flow: Good for organizing multiple clips around characters and scenes
Google Flow can currently create clips from text, first and last frames, reference footage, and other video. Its ingredients are great for bringing characters or key objects to the next segment, and Scenebuilder can arrange, sequence and trim multiple clips.
If your focus is on consecutive scenes and the recurrence of the same character, Flow's reference material and scene organization methods are worth trying first. However, the official also stated that the support duration and functions of different models are not exactly the same; use is also subject to age, subscription and supported region restrictions.
Use a 30-second video to compare, don’t just compare the first one
A truly useful comparison is not to do the same prompt once and then pick the most beautiful cover. Give the three candidate tools the same set of materials and complete a short video of 20 to 30 seconds to record the entire process from start to export.
- Prepare a script of no more than 60 words, a reference picture of a character or product, and a clear horizontal and vertical frame.
- Make three shots respectively: a fixed shot, a subject action, and a camera movement.
- Record how many times each shot is generated before it can be used, and whether the characters, products and background are continuous.
- Arrange the three shots in order, add subtitles and sounds, and then see if you need to switch to another editing software.
- Finally, check the export format, resolution, watermark, consumption quota and material usage rules.
If the first shot of a tool is the most beautiful, but the next two shots keep changing, or the material must be moved back and forth before exporting, it may not be the most time-saving. On the other hand, if the single-segment effect is slightly ordinary but the reference material is stable, the version is clear, and the editing is smooth, it may be more suitable for continuous production.
How to choose
- Just do atmospheric shots or quick exploration: try the text-to-video first, there is no need to set up a complicated process at the beginning.
- If you already have product pictures, character pictures or brand visuals: give priority to the pictures and videos and reference material control.
- Often work on multi-camera content: focus on comparison material management, versions, scene arrangement and subsequent editing.
- The team already uses Premiere: Evaluate Firefly alongside existing Adobe processes.
- Requires repeated construction and automated generation steps: Let’s look at Runway’s workflow method.
Finally, don’t forget the most common layer: who should the video be shown to, where to publish it, how long it needs to be, and whether characters and products must be retained. With these four things written down, software selection usually won't be too difficult.
